Hallmark Channel has renewed its drama series Chesapeake Shores for a third season, one of several programming announcements made during the network’s annual Television Critics Association winter tour dinner event Saturday.

The series, which stars Jesse Metcalfe, Meghan Ory, Treat Willams and Diana Ladd, will return this summer for a 10-episode run, according to network officials.  

 “Viewers have fallen in love with the heartfelt and compelling storylines as each character navigates the complexities of life, love and choices,” said Michelle Vicary, Executive Vice President, Programming and Network Publicity, Crown Media Family Networks in a statement.  “We look forward to continuing and further exploring the multi-generational family journeys that people of all ages can enjoy and relate to, which makes Chesapeake Shores a fitting series for our brand and the quality, family entertainment we provide.” 

The network also announced it will debut the inaugural 2018 American Rescue Dog Show on Feb. 12. The special, hosted by Rebecca Romijn and Rich Eisen, will honor the traits and benefits of mixed breeds and rescued purebreds. In addition to competition in the ring, the show will highlight heartwarming stories of courageous dogs who have overcome tremendous odds to be rescued and find forever homes, said the network.

In addition, Hallmark said it would debut the fourth season of original series Good Witch on April 29.

On the Hallmark Movies & Mysteries front, the network has greenlit development for a new original movie, The Crossword Mystery, created by New York Times crossword editor Will Shortz. The network has tapped Lacy Chabert and Brennan Elliott to star in the film, which follows a crossword puzzle editor who finds her life turned upside down when she is pulled into a police investigation after several of the clues in her recent puzzles are linked to unsolved crimes, said network officials. 

The network has also signed Alexa PenaVega and Carlos PenaVega to star in a new movie penned by Garage Sale Mystery franchise writer Walter Klenhard. In addition, The Garage Sale Mystery franchise will return in August with four all-new original movies. Hallmark Movies & Mysteries will also add long-running USA Network series Psych beginning Jan. 15 to its lineup, running three episodes every weekday from 6-9 p.m. leading out of three episodes of Monk, said network officials.

The traditional one-hour family drama genre, once a staple of primetime TV lineups but in recent years pushed to the backburner by darker, more provocative drama projects, is once again beginning to find its footing with the recent success of two freshman series.

Hallmark Channel’s Chesapeake Shores finished its inaugural campaign last month as the most-watched original scripted series in the network’s history, while broadcaster NBC’s This Is Us has launched this past September as one of the most watched new series of the 2016-17 television season.

TUGGING AT HEARTS

The two shows, with their heart-tugging optimism and relationship-themed plotlines, are going against the grain of today’s most popular scripted series which offer a darker, more sinister and pessimistic view of human nature. Nevertheless, the shows are tapping into an underserved audience of both older and surprisingly young viewers looking for more positive and uplifting programming options, programming executives said.

“There are a lot of great television shows out there but many are darker and edgier and have a supernatural twist,” Hallmark Channel executive vice president of programming Michelle Vicary said. “That’s a great television experience on other networks, but we found that there’s an audience for family dramas, if you do it right.”

Hallmark’s multigenerational family drama Chesapeake Shores, based on a novel series by Sherryl Woods, averaged 2.7 million viewers on a Nielsen live-plus-3 basis during its 10- episode run that ended last month, making it the most-watched original scripted series in network history.

Chesapeake Shores also finished as one of Hallmark Channel’s youngestskewing series, drawing more 18-49 year old female viewers than its other scripted content. Vicary attributed that youth appeal to the strength of Woods’s book franchise, as well as the well-written characters and storylines.

“Chesapeake Shores has proven to us that there is a bigger audience across the board for family dramas than one might think,” she said.

This Is Us, which follows a family of three kids — two siblings and an adopted child with the same birthday — throughout their childhood and adult lives, is arguably the surprise hit of the new television season. Through five episodes, its installments have posted the five highest ratings number among all telecasts of the Big Four networks’ 10 first-year dramas so far this season, according to network officials. The Oct. 25 episode averaged a season-high 8.7 million viewers.

Amy Winter, executive vice president and general manager of family-targeted network UP, believes that the success of This Is Us shows there is an audience yearning for more family dramas.

UP, which this past summer rebranded its service to focus on family-themed programming and acquired the rights to such family-themed dramas as Parenthood, will debut in 2017 its own one-hour family drama, Date My Dad, about three daughters who look to support their widowed father by searching for a companion for him.

“While they do have a certain soapiness to them, I would say that some of the stickiest plotlines that you ever see out there do relate to love and family and relationships that exist within the family,” Winter said. “Usually at the center of those dramas are people that feel like family to you, and you want to root for, and you end up picking your favorites.”

CO-VIEWING APPEAL

Winter also said that the family-drama genre appeals to viewers at the older end of the millennial demographic, age 25-34, who are settling down with families and seeking programming they can identify with to watch along with their kids.

“Some of these noisier, darker high-concept shows are definitely in the zeitgeist right now, but shows like This Is Us are proof that when you have quality storytelling, word of mouth will travel and people will come to it,” Winter said. “There’s also a misperception that the cooler, edgier and darker you go, the more you capture the younger side of this audience, but the quality storytelling in these one-hour dramas goes beyond something that might be more gimmicky.”
